Introduction

The Alldaymall A88X features a 7 inch HD screen that makes up the bulk of the internal hardware. This guide will walk you through the process of removing the existing LCD Screen and installing a new one.

Using a plastic opening tool, carefully pry the device apart. Make your way around the entire perimeter of the device and carefully place the two panels next to each other.

When separating the panels keep an eye out for the power button and volume rocker as they can be dislodged.
